Definitions

• the present invention relates to a device for dispensing liquid products and more particularly, cosmetic or pharmaceutical products, without air intake.
• Distributors of liquid products without return air generally include a tank provided with a movable bottom, an exhaust pipe and a pusher cooperating with a piston and a return spring .
• the distribution method is poorly controlled, which is detrimental to the dosage of the product, in particular when the volumes are low (a few milliliters).
• the present invention aims to solve these problems satisfactorily.
• a device characterized in that it comprises a sealing and metering bushing supporting a shutter needle displaceable in translation in a discharge channel formed on said bushing being connected by a drive rod to an axial guide rod capable of sliding in the exhaust duct of the reservoir communicating with said channel, by pressing on said sleeve and compression of said spring.
• said needle is secured laterally to a set of elastic blades whose free ends are fixed to the sleeve.
• said drive rod is provided with a hinge connecting with said needle allowing its flap in said channel from a deployed molding position.
• said rod is provided with a lateral lug cooperating with a retaining notch formed on the internal wall of the exhaust duct.
• said rod is provided with a longitudinal flat allowing the passage of the product towards the evacuation channel.
• said link consists of a cam of triangular articulated section, in the lower part, respectively on the rod and on the sleeve and, in the upper part, on a beveled end of the needle.
• said channel is provided with deformable upper lips allowing the needle to snap into place.
• said socket comprises a central sleeve forming a piston intended to cover the exhaust duct by delimiting, around said rod and above said duct, a metering chamber.
• said sleeve comprises a peripheral skirt surrounding said spring and carrying in the lower part a flange capable of coming into abutment on the upper part of the reservoir at the end of metering.
• the socket of the invention is produced in one piece with the needle, the link and the rod by injection molding. It is further provided that said socket is associated with a cover forming a push button and closing said discharge channel in the upper part.
• this cover forming a pusher comprises an orifice aligned with the axis of said channel and the internal periphery of which receives the support of the needle in the sealed closure position.
• the device of the invention ensures self-sealing of the dispenser.
• the seal is further reinforced and secured by the action of the elastic blades.
• the link and the rod allow to break down the product distribution mode which is thus carried out in two stages which allows better control of the dosage.
• the metering chamber is arranged outside the product tank and inside the return spring, being isolated by the wall of the sleeve, thereby preserving the product from contact with the metallic elements.
• the device of the invention can be produced in one piece by injection molding and offers a high rate of product return.
• FIG. 1 represents a general view in axial section of an embodiment of the device of the invention mounted on an “airless” dispenser;
• FIGS. 2A and 2B represent sectional views of the embodiment of FIG. 1, respectively, on leaving the mold and after mounting the cover, before assembly on a distributor;
• Figure 3 shows the embodiment of the previous figures in bottom view;
• FIGS. 4A to 4E represent the device of the invention during the successive phases of the distribution of the product.
• the device of the invention as shown in the figures is intended to equip a dispenser for liquid products and more particularly cosmetic or pharmaceutical products, without air intake shown in FIG. 1.
• This product is packaged in a tank R which is provided, at the bottom, with a movable bottom F and, at the top, with a shoulder E carrying a product exhaust duct C.
• the dispenser is also provided with a pusher intended to cooperate with a piston
• the device of the invention as shown in particular in FIGS. 2A and 2B, comprises a sleeve 1 for sealing and metering supporting a shutter needle 2.
• the needle 2 is intended to be housed in an evacuation channel 12 formed here on the upper face of the sleeve 1 after flap and snap-in from the deployed mold outlet position of FIG. 2A, the device here being made in one piece.
• the channel 12 offers, at its upper part, deformable lips 12a projecting partially closing the channel.
• the needle 2 is displaceable in translation in the channel 12 by manual support on the sleeve 1 and compression of the spring S, by being connected by a connecting rod 3 to a axial guide rod 4 which is capable of sliding in the conduit C tank R exhaust during product distribution.
• the drive rod 3 is provided with a hinge 32 for connection with the needle 2 allowing its flap.
• This link consists of a cam 31 of triangular articulated section, in the lower part, respectively on the rod 4 and on the sleeve 1 and, in the upper part, on a beveled end 21 of the needle 2 via the charmère 32.
• the link 3 thus has a pivot axis with each of the adjacent elements.
• the rod 4 is inserted with freedom of sliding in the conduit C while filling its internal volume except at the location of a longitudinal flat 40 (see FIG. 3) allowing the product to pass through said conduit and in the direction of the channel 12.
• the rod 4 is also provided with a lateral lug 41 cooperating with a retaining catch e formed on the internal wall of the conduit C.
• the conduit C communicates with the channel 12 via a metering chamber 10 delimited inside a central sleeve 11, above the conduit C and extending, in the sleeve 1, coaxially with the rod 4.
• the sleeve 11 is intended to cover the duct C in a sealed manner by forming a piston.
• the upper edge of the conduit C will advantageously be provided with a peripheral lip p.
• the needle 2 is laterally secured to a set of two elastic blades 21a, 21b, the free ends of which are fixed to the bush 1 by blocking in slots 20a, 20b, after the needle flap (see FIG. 2B).
• the blades 21a, 21b participate in the recall, guiding and then maintaining the needle in the closed position of the channel 12 (see FIGS. 4A and 4D).
• the sleeve 1 further comprises a peripheral skirt 13 surrounding the spring S and carrying, in the lower part a flange 13a coming, in the final metering phase, in abutment against the shoulder E of the reservoir R.
• the flange 13a also cooperates with a radially projecting rim T carried by the reservoir R and ensuring the retention of the sleeve 1 in its housing as well as the maintenance under tension of the spring S in the sealed closing position of the distributor (see FIG. 4E).
• the device of the invention further comprises a cover 5 forming a push button and closing the channel 12 sealingly in the upper part.
• This cover is, for example, snapped on (as in the variant shown here in the figures) or fitted onto the socket 1.
• the cover 5 comprises a lateral ejection orifice 50, possibly associated with a nozzle, "the internal periphery of which receives support from the end of the needle 2 in the position for sealingly closing the dispenser.
• the internal periphery of the orifice 50 will be provided with an annular ring forming a valve seat for the end of the needle 2.
• the sleeve 11 begins its descent by compressing the spring S and subjecting the rod 3 to a torque in the counterclockwise direction. This movement causes the needle 2 to translate backwards and to withdraw from it relative to the ejection orifice 50.
• the metering chamber is gradually emptied by the piston effect of the sleeve 11 and the scraping of its wall by the lip p of the conduit C causing the product to be delivered through the channel 12 and the orifice 50.
• Figure 4E corresponds to the return phase to the rest position of Figure 4A.
• the relaxation of the manual support causes the spring S. to relax. This relaxation first causes the sleeve 11 and the pusher 5 to rise until the needle 2 abuts against the orifice 50, the rod 4 remaining. immobilized in conduit C.
• the link 3 pivots clockwise and pushes the needle 2 against the orifice 50. This movement is accompanied by the aspiration of the product in the reservoir R and the gradual filling of the chamber 10 inside the sleeve 11.
• the spring S is then kept under slight tension by the early abutment of the flange 13a against the projecting rim T of the reservoir R.
